Calculate Coefficient Of Variation Stock

A neat variation of the tuner.

The panels work as expected. Very good acoustic absorption coefficient (middle-high frequencies). The foam seems durable. I'd like to have a white version.

Great product, really find the variation quite useful in many situations.

S is a variation of the original, it is still very good quality and most useful

It is super clear so you don't notice any color variation.

I like Ilford's products when it comes to film and developing chemicals. At first I had issues trying to calculate how much powder to use to make the amount I need to use for developing ( so I could maximize the shelf life)

[This review was collected as part of a promotion.] Not the ink's fault it ran out way too soon! I didn't calculate the "small" amount of printing our 2 person household actually prints! But works fine in my HP printer, all the way to the last drop!

I wasn't sure if this was going to work well or not but I find it does make it easier to calculate the lighting in my studio. It's very easy to read and use. Helps with realizing the light needed and helps us understand the quality of light. Overall good product that I would recommend if you're thinking about it.

Purchased to use with the C70 - works great and the C70 is able to calculate the record time left. Record time much better than a standard Canon BP-A30 battery more like a Canon BP-A60 battery. The D-Tap works great for an Atomos Ninja V or an Osee T7. Only 2 I tested so far. No issues recharging in the standard Canon BP-A battery charger that came with the C70 - Yes a little long in the back side, but fantastic on a shoulder rig or tripod setup.

I have tried reversing rings on manual bodies in the past and while they are cost effective, they are inconvenient to use since you have to calculate the exposure manually. This extension tube is simple to use but brings the photo so much closer, which is great not only for insects, praying mantids, etc., but for getting closeups of childrens' faces. I should have spent the money years ago.
